API Certification

[MKZman]

In the link, the 2% was not named. Is someone trying to say that a major brand is not providing oils meeting the API claims?

This thread has taken some twists and turns. Maybe we need a thread for each product, and how the use of that specific non-OE product, could possibly effect your warranty. This thread got me thinking about the oil filter type I am currently using...
Back to the API topic...
There are cases, here on this forum, where using non-API certified products, were proven to decrease engine wear and tear, and in some cases, prevent catastrophic failure.
There is no way, as far as I know, that testing for API compliance, on a used oil sample, could possibly be done, or would ever be attempted, or even thought of as an option.

When you make a warranty claim they will ask for receipts which will show which oil you used ...

Just out of curiosity, how many engines haven't been replaced under warranty because of what oil was used?

don't know, but i will tell you that audi was all over me wanting to know what oil i had put in the A6. since it had under 4k when it started getting 500 miles to the quart, it still had the factory fill in it, but i was bloody careful to get all the OCs at the dealers (one of which used 20w-50 in the winter).

it finally went back under the lemon law for unrelated problems, but they did rebuild the engine under warranty (oil control ring upsidedown).
